I need to know first off what the correct coils are for the left and right out holes hit out the balls to your flippers. The manual says simply "game specific" on the parts page. I feel like the current coils are too weak which leads me to my second question. In the manual it shows to metal hole ring inserts in those 2 outholes which this machine doesnt have and maybe this is why the balls barely make it out of the hole if they do at all. My third question is what controls which way the balls get kicked out into an outlane via left or right. 95% go the the right leaving no balls on the left to use. All the switches and sensors work so I am guessing that its something with the cpu but I have no idea. Im trying to help a customer of ours that doesnt have any extra money to spend on a tech so im just shooting him advice after I looked at it for him for free. Any help would be appreciated.
